To be a sister who has made a life-long commitment usually takes six to nine years of preparation. Formation programs vary with each congregation but usually involve the following stages:

Candidate: (1-2 years) time of association with the congregation during which the candidate comes to know the spirit and mission of the community and the community assesses the suitability of the candidate.

Novice: (1-2 years) period of more intense study and formation in the life of prayer and spirit of the congregation during which the novice comes to an understanding of the vowed life.

Temporary Professed: (3-5 year) time of further integration of a life of prayer, community and ministry while living the vows of chastity, poverty and obedience.
